Dear student,
Generally, it is not mandatory to have studied Maths at Class 12 level to pursue BBA as a grduate course. However, if you have studied, it will be an added advantage to you.
Since you expressed interest in LPU, here is the eligibility criteria to study BBA at LPU:
How can I get free seat in LPU?
Does LPU offer admission to the B Pharmacy course? What is its fee structure and admission criteria?
How is the library facility at lpu? Is reading room facility available?
